This optional parameter allows you to specify the node to stop at when
 determining a set of communication paths.

 You may enter either:

     TO = node-name
     TO = osi-net
     TO = osi-area
     TO = ph4-addr
     TO = ph4-area

 where:

     node-name   identifies the terminating node using either the node's
                 full DECdns name or its Phase IV synonym name.

                 For example ".USA.Boston" or "BOSTON".

     osi-net     identifies the terminating node using one of the node's
                 network entity titles (NETs).  This may be entered in
                 the format:

                     afi:idi:predsp-locarea:nodeid:sel

                 For example "43:15084745192:00-0C:aa-00-04-00-50-30:00".

     osi-area    identifies the terminating node using one of the node's
                 network areas.  In this case, the first node found in
                 the area becomes the terminating node.  This may be
                 entered in the format:

                     afi:idi:predsp-locarea

                 For example "43:15084745192:00-0C".

     ph4-addr    identifies the terminating node using the node's Phase IV
                 network address.  This may be entered in the format:

                     area.nodeid

                 For example "12.102".

     ph4-area    identifies the terminating node using the node's Phase IV
                 network area.  In this case, the first node found in the
                 area becomes the terminating node.  This may be entered in
                 the format:

                     area.*

                 For example "12.*".

 If TO is not specified, the terminating node is assumed to be the local
 node.  If FROM is not specified, the starting node is assumed to be the
 local node.  You must specify at least one of these (they cannot both be
 defaulted).

 Example:  SHOW PATH FROM .USA.BOSTON TO .FR.CANNES
           SHOW PATH TO 43:15084745192:00-0C:AA-00-04-00-50-30:00
